We're dividing 124154 by 84 
The aim is to understand the frequency of 84 in 124154.

Going ahead to step 1:
84 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 84

Step 2:
If we divide 12 by 84, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 84

On to step 3:
When dividing 124 by 84, we get 1 with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 84 from 124, we get 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 84

Moving on to step 4:
84 goes into 401 4 times with a remainder of 65.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 65 after subtracting 336 from 401.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 84

Advancing to step 5:
84 can be fit into 655 7 times, resulting in a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Deduct 588 from 655 and we're left with 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 84

Step 6:
The number 84 fits into 674 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 1478.0
Subtract 672 from 674 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 84, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1478.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 84 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 1478.02
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
320 divided by 84 is 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 1478.023
Subtracting 252 from 320 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 10:
680 divided by 84 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 1478.0238
Deduct 672 from 680 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
When dividing 80 by 84, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 1478.0238
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
If we divide 800 by 84, we get 9 and a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 1478.023809
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
84 goes into 440 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 1478.0238095
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
200 divided by 84 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 1478.02380952
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 1478.02380952 with a remaining 3.2e-08.
